Oxygen and light accelerate recovery from SO2-induced inhibition of leaf photosynthesis and from cytoplasmic acidification
(Elsevier GmbH, 2000)
Leaves of several plant species were illuminated either in air or in a gas atmosphere with reduced oxygen content, and photosynthesis and transpiration were recorded after brief exposure to high concentrations of SO2. ...
A new electrolyte based on Tm3+-doped delta-Bi2O3-type phase with enhanced conductivity
(Elsevier Science Bv, Amsterdam, 2015)
The possibility to stabilize the delta-Bi2O3-type polymorph with high ionic conductivity by doping with Tm2O3 was investigated in this study. Five microaystalline samples were synthesized at 750 degrees C from alpha-Bi2O3 ...
Structural and electrical properties of ZnO varistors containing different spinel phases
(Elsevier Sci Ltd, Oxford, 2001)
Structural and electrical properties of ZnO varistors were investigated as a function of spinel composition. Six varistor mixtures differing only in chemical composition of spinel, were prepared by mixing separately ...
Thermal diffusivity and electron transport properties of NTC samples obtained by the photoacoustic method
(Elsevier Science Sa, Lausanne, 2006)
Thermal diffusivity and electron transport parameters of sintered NTC samples were determined by the photoacoustic (PA) technique. Powder mixtures composed of MnO, NiO, CoO and Fe2O3 were milled to nanometer particle size. ...
Mechanisms of detoxification of high copper concentrations by the microalga Chlorella sorokiniana
(Portland Press Ltd, London, 2020)
Microalgae have evolved mechanisms to respond to changes in copper ion availability, which are very important for normal cellular function, to tolerate metal pollution of aquatic ecosystems, and for modulation of copper ...
Selection of assay, organism, and approach in biomonitoring significantly affects the evaluation of genotoxic potential in aquatic environments
(Springer Heidelberg, Heidelberg, 2020)
In this study, few different evaluation concepts were used for the assessment of genotoxic potential at the stretch of the Danube River identified as a significant hotspot of pollution originated through the untreated ...
An insight into chemical composition and bioactivity of 'Prokupac' red wine
(Taylor & Francis Ltd, Abingdon, 2020)
Autochthonous variety 'Prokupac' (Vitis vinifera L.) red wines with the addition of selected aromatic herbs (Artemisia absinthium, Cinnamomum zeylanicum, Glycyrrhiza glabra and Pimpinella anisum L.) were evaluated for ...
Silicon modulates the metabolism and utilization of phenolic compounds in cucumber (Cucumis sativus L.) grown at excess manganese
(Wiley-V C H Verlag Gmbh, Weinheim, 2007)
Cucumber plants (Cucumis sativus L. cv. Chinese long) were grown in nutrient solution with increasing manganese (Mn) concentrations (0.5, 50, and 100 mu M) with (+Si) or without silicon (-Si) supplied as silicic acid at ...
Seasonal variation in metal concentration in various tissues of the European chub (Squalius cephalus L.)
(Springer Heidelberg, Heidelberg, 2019)
Due to the increasing industrialization, metals are discharged into all spheres of the environment, in particular, in river courses, which leads to the need for constant monitoring. Metals do not degrade into harmless end ...
The conformation of epinephrine in polar solvents: an NMR study
(Springer/Plenum Publishers, New York, 2018)
Epinephrine (Epi) is a physiologically important catecholamine. Molecular conformation of Epi controls the interactions with other molecules and its biological effects. There have been a number of theoretical studies ...
